So I just only just started and I was at the wonder trade in hopes for something decent and I got a pokemon called Urayne and as I go to check out the pokemon the game suddenly crashed and now I can't start the game again I get this error:

This is a product of a hacker who messed with the Trade system earlier. Urayne is not in the game yet, so you received a corrupted file. If there is a way to fix it you will have to wait for an admin to reply. Sorry, nothing I can help with =(

Yes, unfortunately this is a result of a hacker sending out corrupted Pokemon that crash your game when you receive them. You will have to delete your save file and start a new one, fortunately it sounds like you didn't get very far. I would stay away from the Wonder Trade for now until we have made sure it is 100% safe.
